Author: gavin Date: Tue Dec 10 13:36:56 2013 New Revision: 259173 URL: http://svnweb.freebsd.org/changeset/base/259173 Log: Merge r258758 (by adrian) from head: Make sure any waiters on the scan results get notified if the scan task decides to do nothing. If this isn't done, then a scan request whilst a scan occurs in an active channel set or a completed channel set will hang. Candidate for 10.0.
